filling the grid

[dirk van waes]

Hello,
I fill an arraylist (ALstudents) with data from a dataset
Therefor, I first made a structure :
Public Structure lldata
Dim NameForname As String
Dim points As String
Dim llremark As String
Dim llnr As Integer
End Structure
Then I filled Alstudents with the data from the dataset, transformed in
lldata

I can adress the data now as follows : Alstudents(2).NameForname

Now I want to bind this arraylist to a dynamic datagrid.
dgstudents.recordsource = Alstudents

Problem is, I get an runtime-error defining new colums in the grid as
folows:
datagridcol.DataField ="NameForname" (as with a dataset)

I get : "A field or property with the name 'NameForname' was not found on
the selected datasource."
I suppose it has something to do with adressing the lldata-structure. I
changed the syntax many times, but nothing seems to work.Can somebody point
me in the right direction on this one?
TIA
Dirk

Hello Alvin,
Thxs for answering.

, transformed in lldata

I read the dataset row per row, and put each row in the structure lldata .
Then I put the structure in the arraylist Alstudents

datagridcol.DataField ="NameForname"
it is a brand new column. The recordsource is an arraylist (Alstudents) with
members of the defined structure lldata. I think the structure is the cause
of my problem!

TIA
Dirk

, transformed in lldata

What does that mean within the context of your problem?

datagridcol.DataField ="NameForname"

How is datagridcol defined? This would work if datagridcol was a brand new
column attached to a new datagrid. However, it will fail if it is a clone
of
an existing datasource.
